The third and final episode, "The Science of Adventure", was released on the Blu-ray and DVD of Toy Story 3. Buzz tells Rex and Hamm about the end of his trip and how he got home in time for the events of Toy Story 3.

Trivia

Each short features Randy Newman's music score of the movie that it is included with.

These shorts presumably take place sometime between the events of Toy Story 2 and Toy Story 3, as Buzz, Rex and Hamm still live at Andy's house. However, his room looks the same as it was when he was a little kid, even though he was a teenager by the time of Toy Story 3. Whether this is canon or not can be debated.
